Why convert MP4 to OGG?
OGG Vorbis is the audio format many game engines, Linux apps and open-source projects prefer, so converting MP4 to OGG is handy for game sound effects, background music and web projects.
- MP4: usually lossy, so quality drops a little each time it is re-encoded.
- OGG: open and royalty-free.
- OGG: good quality at medium bitrates.
For Unity, Godot and similar engines, 160 kbps OGG is a good balance between size and sound.

Does converting MP4 to OGG lose quality?
Only the sound is kept and re-encoded as OGG. Video soundtracks are usually AAC at 128–256 kbps, so choosing 192 kbps or more keeps the OGG sounding the same as the video.
How long does it take?
Fast. Only the sound is decoded, so even a long video usually converts in well under a minute.
What is an MP4 file?
MP4 is a container that usually holds H.264 or H.265 video with AAC sound. It is built on Apple's QuickTime file structure and became an ISO standard in 2001. Because almost every phone, browser, TV and editing app can play it, MP4 is the safest choice when you need a video to just work.
What is an OGG file?
OGG files usually contain Vorbis, a free, open audio codec. Spotify streamed in Vorbis for years, and many games and Linux apps use OGG for music and sound effects.
Frequently asked questions
Do I have to pay or sign up to use the MP4 to OGG converter?
No. There is no account, no payment and no watermark. The only limit is 1 GB per file, set by what browsers can handle.
Is my file uploaded to a server?
No. The converter runs inside your browser using WebAssembly, so your file is processed on your own device and never sent to us or anyone else.
Will the OGG sound as good as the MP4?
Only the sound is kept and re-encoded as OGG. Video soundtracks are usually AAC at 128–256 kbps, so choosing 192 kbps or more keeps the OGG sounding the same as the video.
Can I convert OGG back to MP4?
Yes, use the MP4 Converter and choose MP4 as the output.
An MP4 plays without sound. What should I do?
The audio may use a codec your player does not support (for example AC3). Convert it to MP4 again so the sound becomes AAC.
Can I use it on my phone?
Yes. Open the page in your phone's browser and choose a file. Phones have less memory than computers, so very large files are better converted on a laptop or desktop.
